TKR6501B Chassis (revised, 7075, 3mm, hard anodized, lightened, ET410 EB410)Developed for the rigorous demands of the ET410, this new chassis has received improvements to increase its durability and lifespan. By making small changes to a few key areas, we were able to directly link the A block with the chassis. With this change, most of the force from an extreme frontal impact is transferred into the chassis, resulting in a tougher front end assembly. Chassis wear characteristics have also improved by slightly reducing the height of the B block, allowing for more material at the chassis kickupTKR6051B is also backward compatible with the EB410 when used with the hinge pin braces mentioned below
